TMZ reports that Naya and Lea have been feuding on the set of Glee and the problem has gotten so bad that one of them stormed off set recently and filming had to be shut down for the day.

Everyone seems to agree that one of the actresses bolted from the set putting production behind schedule, but there are conflicting reports as to who made the exit and why.

Naya's story (and the more believable version of events) is that cast and crew were getting fed up with Lea's diva-like behavior, as she reportedly kept putting scenes on hold to take phone calls or attend to personal matters.

Seeing that no one else planned on speaking up, Naya approached producers and informed them that everyone was fed up with Lea's behavior.

Sources say Lea caught wind of Naya's complaint and angrily left the building.

Naturally, insiders close to Lea deny this story and say the two actresses weren't even shooting scenes together on the day and question and producers asked Naya to leave the set for reasons that had nothing to do with Lea.

And here we thought all the good drama was taking place on camera. Hopefully these ladies settled their differences in song.
